    Abstract:
    OBJECTIVE: The purpose of this study was to determine the frequency of and factors associated with performing one therapeutic operation after percutaneous diagnosis of nonpalpable breast cancer. MATERIALS AND METHODS: Retrospective review was performed of records of 350 consecutive women who had therapeutic surgery after percutaneous imaging-guided core biopsy diagnosis of nonpalpable breast cancer. Records were reviewed to determine the frequency of performing one operation and associated factors. Statistical analysis was performed. RESULTS: One operation was performed in 283 (80.9%) of 350 women, including 106 (95.5%) of 111 women who had mastectomy and 177 (74.1%) of 239 women who had breast conserving surgery. At bivariate analysis, one operation was significantly more likely in women who had no underestimation (p < 0.001), mastectomy rather than breast conservation (p < 0.001), axillary dissection during the first operation (p < 0.001), percutaneous diagnosis of infiltrating carcinoma (p = 0.001), or mammographic mass (p = 0.006). At multivariate analysis, one operation was significantly more likely if underestimation was absent (odds ratio [OR] = 10.1, 95% confidence interval [CI] = 4.2-24.7) or if mastectomy was performed (OR = 8.7, 95% CI = 3.2-23.5); for women who had breast-conserving surgery, one operation was significantly more likely if underestimation was absent (OR = 11.4, 95% CI = 3.9-33.2) or if a mammographic mass was present (OR = 2.4, 95% CI = 1.3-4.6). CONCLUSION: One operation was performed in 80.9% of women with percutaneously proven nonpalpable breast cancer, including 74.1% of women who had breast-conserving surgery and 95.5% of women who had mastectomy. Among women who had breast conservation, one operation was significantly more likely if histologic underestimation was absent or if a mammographic mass was present.
